Switcher is an Umbraco package that provides a new property editor that works as an alternative to the core's true/false datatype.

Once the package has been installed, create a new datatype using the "Switcher" property editor, edit the settings to your needs and add it to a doctype.

The great thing about Switcher is that it gives the content editors a better visual aid as to whether or not a property is true/false, as well as providing a touch friendly property for any content editor who prefers to use a tablet.
